Answer:
400 Joules
Explanation:
From the question,
The total kinetic energy of the water balling when hits the ground is given as
K.E = 1/2mv².................. Equation 1
Where K.E = Kinetic Energy of water ballon, m = mass of water balloon, v = velocity of water ballon
Given: m = 2 kilograms, v = 20 meters/second.
Substitute these values into equation 1
K.E = (2×20²)/2
K.E = 2×400/2
K.E = 400 Joules

Answer : The volume of calcium hydroxide is, 32.89 ml
Explanation :
Using neutralization law,
where,
= basicity of an acid = 1
= acidity of a base = 2
= concentration of hydrobromic acid = 0.389 M
= concentration of calcium hydroxide = 0.0887 M
= volume of hydrobromic acid = 15 ml
= volume of calcium hydroxide = ?
Now put all the given values in the above law, we get the volume of calcium hydroxide.
Therefore, the volume of calcium hydroxide is, 32.89 ml
b. Evaporate minerals are more soluble than calcite and quartz.
c. Evaporate minerals are more soluble than quartz and less soluble than calcite.
d. Evaporate minerals are less soluble than quartz and calcite.
Answers
Answer:
Evaporate minerals are more soluble than calcite and quartz.
Explanation:
Evaporate minerals are the water soluble minerals which at higher concentration precipitate out and crystallized forming rocks.
example of chemicals present are:
chlorides and sulphates.
Quartz is silica (very less soluble, or insoluble)
Calcite is calcium carbonate, again an insoluble salt.
Thus
Evaporate minerals are more soluble than calcite and quartz.

The numbers in scientific notation are 291.7 = 2.917 × 10₂ and 0.0960 = 9.60 × 10⁻².
Scientific notation is commonly used in scientific and mathematical calculations, as well as when dealing with very large or very small numbers. It allows for a more compact and manageable representation of these numbers.
To write the numbers in scientific notation, we need to express them in the form of "a × 10^b," where "a" is a number between 1 and 10, and "b" is an integer.
For the number 291.7, write it in scientific notation as:
291.7 = 2.917 × 10²
For the number 0.0960, write it in scientific notation as:
0.0960 = 9.60 × 10⁻²

Answer: 500K and 0.10atm
Explanation:
An important concept to remember is that gases behave most ideally under low pressure and high temperature. 500 K is a high temperature and 0.10 atm is a low pressure, which makes that the best answer.
Final answer:
The conditions under which H2 gas would behave most like an ideal gas are at a high temperature of 500 K and a low pressure of 0.10 atm. These are optimally suitable for a gas to behave ideally as per the ideal gas law.
Explanation:
Under the conditions of both temperature and pressure given in the question, H2 gas would behave most like an ideal gas at 500 K and 0.10 atm. The ideal gas law, which describes the relationship between the pressure, volume, and temperature of a gas, suggests that a gas behaves most ideally at low pressure and high temperature.
This is because at low pressures, the volume of individual gas molecules relative to the total volume of gas becomes negligible, and intermolecular forces become weak. Meanwhile, at high temperatures, the kinetic energy of the gas molecules becomes high enough to overpower any intermolecular forces of attraction. Hence, the gas behaves more ideally.
A good way to visualize this is to think of an ideal gas as perfectly 'free' – the particles move in straight lines until they hit the edge of their container, and they do not attract or repel each other. The closer we get to this scenario, the more 'ideal' the gas would behave.

d. What is the average atomic mass of titanium on that planet?
e. I got 46.9 amu but it is wrong.
Answers
Answer:
Average atomic mass = 46.91466 amu
Explanation:
Step 1: Data given
Isotopes of titanium
46Ti = 70.900% ⇒ 45.95263 amu
48Ti = 10.000 % ⇒ 47.94795 amu
50Ti = 19.100 % ⇒ 49.94479 amu
Step 2: Calculate the average atomic mass of titanium
Average atomic mass = 0.7090 * 45.95263 + 0.10 * 47.94795 + 0.1910 * 49.94479
Average atomic mass = 46.91466 amu
